使用laravel将数组数据(动态)传递到chart.js,此“数据:[65、59、80、0、56、55、40]”,其中包含数字应包含来自数据库的信息。

<canvas id="myChart" width="400" height="250"></canvas>

    var canvas = document.getElementById('myChart');
var data = {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
        {
            label: "My First dataset",
            fill: false,
            lineTension: 0.1,
            backgroundColor: "rgba(75,192,192,0.4)",
            borderColor: "rgba(75,192,192,1)",
            borderCapStyle: 'butt',
            borderDash: [],
            borderDashOffset: 0.0,
            borderJoinStyle: 'miter',
            pointBorderColor: "rgba(75,192,192,1)",
            pointBackgroundColor: "#fff",
            pointBorderWidth: 1,
            pointHoverRadius: 5,
            pointHoverBackgroundColor: "rgba(75,192,192,1)",
            pointHoverBorderColor: "rgba(220,220,220,1)",
            pointHoverBorderWidth: 2,
            pointRadius: 5,
            pointHitRadius: 10,
            data: [65, 59, 80, 0, 56, 55, 40],
        }
    ]
};

function adddata(){
    myLineChart.data.datasets[0].data[7] = 60;
  myLineChart.data.labels[7] = "Newly Added";
  myLineChart.update();
}

var option = {
    showLines: true
};
var myLineChart = Chart.Line(canvas,{
    data:data,
  options:option
});

我正在测试数据库中的数据,我知道我的数组包含数据,但是在chart.js中显示为空白
